RELATED APPLICATION

This application claims priority to U.S. Patent Application Ser. No. 63/153,801, filed Feb. 25, 2021, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates to the fields of portable cabinetry. In particular, the present application relates to a portable cabinet with utilities that may be easily transported and installed in a variety of situations.

BACKGROUND

While most homes include kitchens and bathrooms having at least a sink and lighting, there is often an interest in providing these features in non-traditional locations in and around a house or other residence. In addition, these features may be needed on a temporary basis, without requiring extensive remodeling or a permanent installation, as is typical for a kitchen or bathroom.

For example, a family member may move into a home temporarily and request a small kitchen in a bedroom or similar location. A college dorm may have a need to create temporary housing in lobbies or other locations where students would need to be able to prepare meals individually. Other locations may benefit from a portable cabinet having power, lighting and water, such as a bar, a garden shed or a fish cleaning station, for example. In addition, a user may have interest in repurposing the portable cabinet by changing its configuration for different uses.
